Exhaust emissions in residential areas with different street network configurations

The differences in fuel consumption and exhaust emissions for residential areas with different street network designs were investigated. Five areas with three different designs, including a traditional grid network and designs feeding the traffic in from a surrounding street and from a centrally located street, were considered. Differences in total fuel consumption and amount of exhaust emissions were analyzed with an emission simulation model. Linear regression analysis was used to investigate differences in pollution rates. Configurations with centrally located feeding of traffic were found to have higher pollution rates, while configurations with feeding from a surrounding street generate higher emissions per person and higher fuel...
